In this course, you will learn to build your own custom modules for Drupal. Covering the Drupal 8 core API, you'll discover the most commonly-used Drupal hooks, services, and functions and find out how to use Drupal's documentation to learn about the rest. You'll develop several modules step-by-step, while following best practices to ensure maintainability and interoperability with other modules. This course is taught by a practicing Drupal developer and will take a pragmatic approach to development based on real-world experience.

How is it taught?
The class will consist of four weekly video lessons, each around 3.5 - 4 hours long, and four weekly live Q&A sessions with the instructor. The lessons will cover the topics listed below and can be watched on-demand, anytime that is convenient for you. At the end of each lesson, you will be given an assignment to practice what you've learned. (We will provide web hosting for your practice work, so you don't need to worry about setting that up.)
The weekly live sessions will be conducted online, using the webinar software GotoMeeting. During the sessions, the instructor will answer all your questions from and will help troubleshoot any issues you have doing the assignment. (GotoMeeting allows us to view your computer, and take control of your keyboard and mouse if needed. So, we can see any error messages that you're seeing and figure out how to fix it right on the spot.) In addition to the live sessions, you will have access to an online forum to discuss assignments with other students and ask the instructor questions during the week.
After the course is over you can continue to access the lesson videos, free of charge, forever. There are no monthly subscription fees. Just come back and watch the lessons whenever you want. They are a great reference when you forget how to do something.
